TocZZ whom it may concern Be it known that I, CHARLES J. BOND, citizen of the United States, and resident of Syracuse, in the county of,v Onondaga and lState of New York, have im-'entedcertain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates to typewritingmachines and more particularly to type bars and hangers therefor.

lOnel object of my invention is to provide a simple and efficient type bar and hanger const1 action which occupies but little space latepalky., whereby a large number of' type 'bars and hangers may be mounted in a comwithout undulyv paratively small space l crowding the parts or detracting'from the strength or rigidity thereof. v

A further object of the' invention is to provide a type bar and hanger construction in -which dust is excluded from the bearings of the type bar and an `easy running hall bearing construction is afforded and whereinthe parts may be readily assembled and an adjustment thereof afforded ,to coinpensate for wear and o properly position the type bar relatively to the hanger.

To the above and other ends, which will hereinafter appear, my invention consists 'in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the'various views, Figure 1 lis a front to rear vertical sectional view of suicient number of parts of one form of typewriting machines to illustrate my invention in its application thereto. Fig. 9 is a fragmentary enlarged detail sectional view of the type bar and hanger cons-trim tion, the section Vbeing taken on the line w-w of Fig. 8 and looking iu the direction of the arrow at said line. Fig. 3 :is a like View of the sam the section being taken on the line y-y of Fig. 2 and lookingin the direct-ion of the arrow atsaid line. Fig. Jr

is a fragmentary transverse sectional vieiv of two of the type bars and hangers.`

mounted in the segment, the section being taken on the line e-.-e of Fig. 1, and looking in the direction of the arrow at said line.

Fig. -is a detail face view of the hall-separator. Fig. 6 is a det-ail planvieiw partly 1n section, of the typeibar Aand hanger coIistruction represented in the preceding figures. Fig. Z is a fragmentaryenlarged side elevation ofthe type bar andhanger construction represented in Figs. 1 to 6 of the drawings and with one of the side arms of the hangers broken away. 8 is a detail perspective view ofone of thehearing rings. Fig. 9 is ay View which corresponds to Fig. 6, the -view showing a modified form of construction. i liig.` 10 is an Ienlarged detail fragmentary side viewof the hanger employed in the construction shown I* have shown my invention applied to a Monarch 9 typewriting machine, andjwhile the invention is particularly applicable to a visible 7 writing machine wherein a large number of type bars are mounted ina comparatively small space or are,k it should be understood that the invention maybe em- .ployed in various characters of writing machines.

' The frame 1 of the machine is provided with corner posts 2 and a top plate 3 on which a suitable carriage (not shown) is adapted to travel. Said' carriage carries a platen Ll, diagrammatically illustrated in Fig. 1. Key levers 5 are pivoted at G in the base of the machine, and each key lever is provided with a finger key 7 and a restoring spring 8. Key levers are eachvpivoted ai to a sub-lever 10 that .is slot-ted at itsy lower portion as indicated at 11A for coperation' with a fixed fulcrum bar 1Q. 'The upper end of each sub-lever is pivoted at 13 to one end of a link 14, the forward end-of which is pivoted at 15 to a type lbar 1 6 that is pivotally supported upon hangers secured to a type bar segment 17 so as to vibrate upwardly and reainwardly,r and impact with the front face of the platen la `Each type har has an. eye 18 that internally threaded at 19 for cooperation with the bearing rings or plates 20 externally threaded at 20?, each plate being provided with a ballv bearing surface 21 and with Spanner openings 22,

by means of which the rings maybe adjusted in the threaded hearing int-he eyef'f the type bar. lhe ball bearing surfaces 21 of the bearing rings are beveled invopposite directions so as to form a substantially V- shaped raceway between their. for copera- 4tral` threaded opening 28 that coperates as .illustrated in Fig. 3. These bearing rings or aperturedplates are spaced apart and are adapted to receive a ball spacer or separator 2li Within the space 25 between said rings or plates. Extending through the eye of the type bar and through the bearing rings isa hub 26-that is cylindrical in form and has a .central or median ball race or groove 27 therein, said groove being substantially V- shaped in cross-section- This hub has a cenwith. the stems of headed screws 29`which extend in opposite directions through openings in the arms of the type bar hangers 30.

lEach \hanger is preferablymade ofl sheet 1 metal land is of looped form and consists of "the bent or looped portion 3l and side armsy and type bar are free from contact with the hanger-at all times; and that the type bar is wholly supported in place by thel anti-frictionballs 23. It will be understood that the heads of the screws 29 coperate with the arms ofthe hanger to force them into contact with the hub and to cause them to bind against the hub and thus securelyconnect it to the arms of the hanger.

From an examination 'of Figs. 3 and 7 it will be seen that the diameter of the hub is such that a bare clearance is lett between the hub and bearing rings; that this small space 33 is the only opening to the ballbearings;

(that the arms of the type bar hanger break joint with and cover the openings 33 so as to prevent the admission of dust or grit to the bearings; that a simple and eiicient ball bea-ring construction is provided 'wherein dustis excluded from the bearings of the ltype bar, and that access may be readily at tained for adjusting the bearing rings 20 in order to properly center the type bar, 'so that it will occupy a median plane with reference to the hanger and the ball race formed between the eye of the type bar and its hanger.

There is no tendency for the hub or bearing rings to become dislodged in' the operation of the type bars, inasmuch as the hub and rings do not bear at any point .upon a relatively movable part other than the antifriction balls. Furthermore, the bearing lrings or plates are maintained wholly within the eye of the type bar and the means for adjusting the bearings do not therefore oc- Cupy any room in-addition to the width of the type bar.

The bifurcated portion or arms 32 of each hanger are received within radial slots 34 in the type bar segment 17, and that the segment has a threaded opening 35` between each pair of slots 34 for the reception of a hanger. The stem of a headed screw 36 is received -Within an opening 35 in the type bar segment and the head of the screw bears against the face of the hanger 30, as represented in Fig. l, and secures it in position. It will be understood Ithat by this construction an individual adjustment of each type bar hanger in its bearing slots .is afforded and vthat the associated screw 36 securely holds the hanger in its acl'fusted position. Furthermore, the heads of't e screws 36 extend toward the front of the machine and are readily accessible in order to afford an adjustment of the type bar hangers.

i VIn the construction represented in Figs. 9 vand 10 of the drawings, a substantial `reversal of the construction hcreinbefore describedv is effected. That-is to say, in this modified construction, the type'bar hanger 30' is formed with an eye 18a that is internally threaded to receive externally threaded bearing plates or rings 20a. These rings are constructed and adjusted 'in the same manner as the rings 20 in the construction hereinbetore described; they are spaced apart to receive a ball spacer or separator 24 and cooperate with anti-friction balls 213il which likewise cooperate with the hub 2G, said hub being constructed in essentially the same manner as the hub 26 and secured by screws 29a to the bifurcated portion or arms 32 formed on the type bar 16a. V

' The bearing rings 2l or 24 or the hub 26 or 26a may be hardened independently of the other parts of the construction and atterward connected thereto when the parts are assembled and aiiord an etlicient bearing for the type bar and one in which the ordinary wear'upon the parts is resisted. Furthermore, the extensive, bearing afforded for the type bar upon the anti-friction balls tends to prevent any lateral vibration of the type bar on its hanger, thus assuring perfect alinement of the written characters.

It will also be observed that in both forms of the construction shown the parts constituting the ball bearing may be assembled and properly united before the type bar and hanger are connected together and that an adjustment of the ball bearing may be effected at yany time independent-ly of the means by which the type bar andhanger are connected together'.

Various changes may be made in t-he construction without departing from the spirit of my invention.
